Most modern vans, including those at Kuperus, are equipped with AdBlue.
AdBlue is the registered trade name for AUS32, a 32.5% solution of urea in demineralized water, used as an additive in diesel vehicles to reduce emissions. The trademark is owned by the German automotive industry association (VDA).
AdBlue is stored in a separate tank in trucks, buses, and tractors. The fluid is injected into the hot exhaust gases before a special catalyst. The nitrogen oxides produced during combustion are converted into nitrogen and water. AdBlue consumption is approximately 3 to 5% of diesel consumption.
Do I have to pay for fuel or AdBlue myself if I have 100 kilometers free per day?
